Resolving Gradle Dependency Errors in Unity: A Step-by-Step Guide

If you’re a Unity developer trying to use Firebase, Google Play Services, or Unity Mediation and have recently encountered dependency resolution issues, you’re not alone. Many developers face challenges with Gradle dependencies, especially after making changes to their project, such as installing and then removing packages. These errors can grind your development process to a halt, leaving you frustrated. But don’t worry, in this post, we’ll walk through the steps to resolve these Gradle dependency issues effectively.

Understanding the Problem

Recently, users have reported that their Unity projects started failing to fetch dependencies after installing a package related to Unity Mediation. Even after removing the problematic package, developers still encountered persistent errors when trying to resolve necessary components. Here’s an overview of what typically happens:

Error Notifications: During the build process, various dependencies, including those for Firebase and Google Play Services, fail to load.

Missing Components: Error logs can often indicate missing Android components related to mediation, Firebase services, or Google Play functionalities.

Ignored Resolutions: Attempts to simply reimport packages or force resolve dependencies might not resolve the underlying configuration problems.

How to Solve Dependency Issues

Step 1: Enable Custom Main Gradle Template

Open your Unity project in the Unity Editor.

Navigate to Edit Project Settings Player.

Under the Publish Settings, activate the Custom Main Gradle Template checkbox.

This step ensures that you can create a custom configuration for your Gradle dependencies.

Step 2: Force Resolve Dependencies

Go to the Project tab in Unity.

Navigate through Assets PlayServicesResolver Android Resolver.

Click on Force Resolve.

By forcing a resolve, Unity attempts to fetch the missing dependencies from your project’s configuration.

Step 3: Build Your Project

Now, retry building your project. With the earlier settings, you should find that Android dependencies are no longer included directly in your project.

Additional Configuration for Gradle Build Issues

If you still encounter Gradle build issues even after forcing resolutions, follow these steps:

Back in Unity, navigate to Edit Project Settings Player Publishing Settings.

Check the Custom Gradle Properties Template checkbox.

With the path visible below the checkbox, add the following lines at the end of the generated properties file:

Save and try to build your project again.

Conclusion

By following these organized steps, you should be able to resolve Gradle dependency issues in Unity related to Firebase, Google Play Services, and Unity Mediation. Don’t hesitate to revisit these configurations if you make further changes to your project or encounter new packages. This guide aims to provide clarity and a smoother workflow for Unity developers looking to troubleshoot common dependency problems.

Happy developing!
